[0001] The utility model relates to the technical field of laser marking instruments, in particular to a tool for centering judgment and adjustment of water bubbles of laser marking instruments. Background Art
[0002] Laser marking instruments usually have a laser module and a bubble. The laser module is used to emit laser lines, and the bubble is used to help users judge the accuracy of the laser line. During use, when the bubble in the bubble is in the center position, it indicates that the accuracy of the laser line meets the requirements. Therefore, laser marking instruments must match the position of the laser emission line with the center position of the exposed bubble before leaving the factory, so that users can judge whether the laser line is in the best position for accuracy by observing the center position of the bubble and implement horizontal or vertical calibration. Therefore, the quality of the instrument's laser line accuracy is directly related to the accuracy of the bubble when adjusting the center position. At present, in the conventional bubble centering judgment and adjustment process, there is a lack of special tooling, and it mainly relies on human eye judgment, that is, the worker observes whether the bubble of the bubble is in the center position with the naked eye.

[0022] The technical solution of the present invention will be more clearly and completely explained below by describing the preferred embodiments of the present invention in combination with the accompanying drawings.
[0023] like Figure 1 and Figure 2 The preferred embodiment shown is a schematic diagram of the centering judgment and adjustment tooling for the bubble of the laser marking instrument of the utility model. Generally, the laser marking instrument includes a core part 1, which is the core component of the laser marking instrument, including a laser module 11, a bubble unit 12, and a bubble adjustment mechanism 13, and the three are pre-assembled together. The laser module 11 can emit a laser line to project a mark on the target object. The bubble unit 12 is used to help the user judge the accuracy of the laser line, and it has a bubble 120 that shows whether the bubble unit 12 is centered. When the bubble 120 is in the middle position of the bubble unit 12, it indicates that the bubble unit 12 is in the middle position, and it also indicates that the laser line meets the accuracy requirements; when the bubble 120 is not in the middle position of the bubble unit 12, but deviates from the middle position, it indicates that the bubble unit 12 is in a non-center position, and it also indicates that the laser line does not meet the accuracy requirements. Therefore, the center position of the bubble unit 12 must correspond to the laser line accuracy of the laser module 11, so that during use, the user can determine whether the laser line meets the accuracy requirements by observing whether the bubble unit 12 is centered. Therefore, in order to ensure that the center state of the bubble unit 12 corresponds to the laser line accuracy of the laser module 11 when the laser marking instrument leaves the factory, the laser marking instrument will go through a process of determining whether the bubble is centered before leaving the factory. Currently, this process is generally performed by workers using the naked eye to check whether the bubble is centered, so the error is large and the accuracy is low; if it is observed that the bubble is not centered, it is time-consuming to adjust and is greatly affected by human factors.
[0024] The centering judgment and adjustment tool of the utility model includes a light source 2 and a bubble position judgment device 20, the light source 2 is arranged above the bubble unit 12, and the bubble position judgment device 20 is arranged below the bubble unit 12. The bubble position judgment device 20 includes a light intensity sensor 3, a main controller 4, and an indicator 5. The light intensity sensor 3 is arranged below the bubble 120, and is used to sense the light intensity of the light emitted by the light source 2 after passing through the bubble unit 12. The main controller 4 receives the light intensity signal from the light intensity sensor 3, and judges whether it exceeds the preset light intensity range, and the indicator 5 displays the judgment result of the main controller 4.
[0025] When the tooling of the utility model is used, the core part 1 is first placed horizontally so that the bubble unit 12 is in a roughly horizontal position. Then, a light source 2 is arranged above the bubble unit 12 so that the light emitted by the light source 2 can irradiate the bubble unit 12. A light intensity sensor 3 is arranged below the bubble 120 to sense the light intensity of the light emitted by the light source 2 after passing through the bubble unit 12, and transmit it to the main controller 4. When the sensed light intensity is within the preset light intensity range, the main controller 4 determines that the bubble unit 12 is in the center position, and issues a prompt that the bubble is in the center through the indicator 5; conversely, when the sensed light intensity exceeds the preset light intensity range, the main controller 4 determines that the bubble unit 12 is not in the center position, and issues a prompt that the bubble is not in the center through the indicator 5.
[0026] like Figure 3 As shown, the light L emitted by the light source 2 is irradiated on the bubble unit 12, and after being blocked by the bubble 120, an elliptical shadow S is formed below the bubble unit 12. When the shadow S covers the light sensor 3 and is aligned with the light sensor 3 in the center, the light intensity sensed by the light sensor 3 is the minimum light intensity value a. A light intensity deviation value p is set on the basis of the minimum light intensity value a, thereby obtaining a light intensity range (a, a+p). This light intensity range not only takes into account the slight deviation of light intensity sensing, but also meets the product standard requirements of the laser marking instrument. Therefore, when the light intensity sensed by the light sensor 3 is within the light intensity range (a, a+p), it indicates that the bubble unit 12 is in the center position and corresponds to the laser line accuracy. Then, the core part 1 is a qualified semi-finished product and can directly enter the assembly process of the housing of the laser marking instrument, thereby forming a finished product of the laser marking instrument. In this embodiment, the deviation value p is selected from 1 to 8, preferably 5. In other embodiments, the deviation value can be set according to the standard requirements of specific products.
[0027] like Figure 4As shown, when the shadow S cast by the light L emitted by the light source 2 after passing through the bubble 120 does not completely cover the light sensor 3, the light intensity sensed by the light sensor 3 is relatively large. When it is large enough to exceed the light intensity range (a, a+p), it indicates that the bubble 120 is not in the middle position of the bubble unit 12, that is, the bubble unit 12 is in a non-centered position, which does not correspond to the laser line accuracy. At this time, the movement part 1 is an unqualified semi-finished product and cannot enter the assembly process of being assembled to the housing of the laser marking instrument, but needs to enter the adjustment process of adjusting the bubble to the center.
[0028] Preferably, the light source 2 is arranged at 200-300 mm above the bubble unit 12, and the illumination intensity of the light source 2 is 2000-3000 Lux. Here, the distance setting between the light source 2 and the bubble unit 12 and the selection of the illumination intensity of the light source 2 enable the tooling of the utility model to have a suitable illumination intensity during the application process, which can not only meet the illumination requirements of the judgment process, but also will not be affected by the ambient light and cause the accuracy of the judgment. In this embodiment, the light source 2 uses an incandescent lamp with an illumination intensity of 2500 Lux. When the bubble unit 12 is not placed under the light source 2, the illumination intensity sensed by the illumination sensor 3 is ≥2500 Lux; when the bubble unit 12 is placed under the light source 2, but the bubble 120 is not in the center position, the illumination intensity sensed by the illumination sensor 3 is <2000 Lux. According to the tilt position of the bubble 120, the light intensity varies in the range of 1000-1500 Lux. The more centered the bubble is, the smaller the light intensity value is. When the light intensity value is minimum, the bubble is in the center position, and the main controller 4 automatically records the minimum light intensity value a in the current cycle.
[0029] Combination Figure 1 and Figure 5 As shown, the centering judgment and adjustment tool of the utility model also includes a display screen 6, and the light intensity sensor 3 transmits the sensed light intensity signal to the main controller 4. The main controller 4 displays the light intensity value corresponding to the light intensity signal through the display screen 6, and judges whether the light intensity exceeds the preset light intensity range (a, a+p). When it does not exceed the light intensity range, the main controller 4 controls the qualified indicator 51 of the indicator 5 to light up, and when it exceeds the light intensity range, the main controller 4 controls the unqualified indicator 52 of the indicator to light up, thereby giving a clear judgment result prompt to the worker. Optionally, the bubble position judgment device 20 can also include a lithium battery 7 and a battery charging module 8, and the lithium battery is used to provide power to the entire device.
[0030] Preferably, in this embodiment, the light sensor 3 uses a ROHM ambient light sensor chip BH1750FV, which has the advantages of high resolution and wide range (1-65535lux), and the spectral range is similar to that of the human eye, which is suitable for replacing the human eye in this tooling. The light sensor 3 communicates with the main controller 4 through IIC mode, and the current light intensity value is displayed in real time through the OLED display 6, thereby reducing the subjective error of the operator during previous adjustments.
[0031] Combination Figure 2 and Figure 6 As shown, the adjustment mechanism 13 of the movement part 1 includes a pair of adjustment screws 131 and a bubble support 132, wherein the pair of adjustment screws 131 are respectively arranged below the two ends of the bubble unit 12, the bubble support 132 is fixedly connected to the bubble unit 12, and the bubble support 132 and the adjustment screw 131 are in contact and matched with each other through the inclined surface structure 130. When the bubble 120 deviates from the middle position of the bubble unit 12, the operator rotates one or two of the adjustment screws 131, and the bubble support 132 and the bubble unit 12 are driven to move up and down through the inclined surface structure 130, so that the bubble 120 moves to the middle position. In this adjustment process, the operator can rotate the adjustment screw 131 while observing the light intensity value displayed on the display screen 6, so that the effect of the adjustment can be clearly and accurately known, reducing the error caused by the subjective judgment of the operator in the prior art.
[0032] Preferably, the core part 1 also includes a laser module adjustment mechanism, which includes a pair of adjustment screws 141 for an operator to adjust the position of the laser module.
[0033] The above specific implementations are only descriptions of the preferred implementations of the utility model, and do not limit the protection scope of the utility model. Without departing from the concept and spirit of the utility model, various modifications, substitutions and improvements made by ordinary technicians in this field to the technical solution of the utility model based on the text description and drawings provided by the utility model should all fall within the protection scope of the utility model. The protection scope of the utility model is determined by the claims.
